After I contacted "HomeAdvisor" for leads for tree removal a week ago, I got a call from this number.  It had the standard cold-calling characteristics:  You answer, and then wait several seconds for some clown to pick up (that's rude).  The caller claimed to be referred by HomeAdvisor. Then, he said he was some sort of cleaning company, and since they were doing work on "(my street and zip code, but no address)", he had a special price for me.

Since my street is only one block long, I knew this was a lie.
